Core Aeration and Overseeding Keeps Your Lawn Happy

Core Aeration and Overseeding Keeps Your Perkasie, PA Lawn Happy


Pennsylvania’s clay soil gets packed down thanks to lawn mowers, foot traffic, and hot days. 

Compact soil makes it challenging for water, oxygen, and nutrients to reach deep, leaving turfgrass with shallow roots. This is terrible news for your grass, which struggles to find the moisture and food it needs, especially in the winter.

That’s why your lawn needs core aeration and overseeding services.

The Science Behind Core Aeration

Aeration is all about making tiny holes in your soil. At Jamison Lawn Care, we use a professional grade aerator to pull 3” soil plugs out of the ground so air, water, and nutrients can better penetrate the soil. 

Aeration also breaks up compacted soil so turf roots can grow deep into the ground.

And don’t worry about those soil plugs. Once it rains or you turn on your lawn sprinkler, those plugs will dissolve into the ground.

We provide core aeration and overseeding services to our Montgomery and Bucks Counties’ customers in the fall and early spring. Since southeastern PA has cool season grasses that grow in colder temperatures, core aeration helps prepare the soil to receive turfgrass seed.

Core aeration provides four additional benefits:

  • Improves water drainage; you shouldn’t see rainwater ponding on your lawn.

  • Provides improved soil absorption that leads to less water usage.

  • Enhanced fertilizer capability; we put down less fertilizer because it goes deep into the soil.

  • Removes thatch while aerating the soil. Too much thatch harbors disease and insects.

Why Aeration Is Important for Soil Health

As stated above, aeration is vital for soil health because it breaks up compacted soil. This helps water, nutrients, and oxygen get deep into the ground. It also gives roots more room to grow. 

Aeration is like a tune-up for your soil, helping turfgrass grow stronger roots and dense turf aboveground.

If you have yard drainage issues, it could be caused by soil compaction because the topsoil acts as a barrier. Water sits on your lawn rather than draining into the soil when it rains. You may also notice runoff and erosion because of compacted soil. 

The same goes for fertilizer; it can’t go deep into the soil because the topsoil is compacted, closing off the ability for fertilizer to penetrate the soil.

Soil compaction leads to a lack of air that suffocates beneficial soil microbes that can’t break down thatch and nutrients, leading to root diseases.

When the core aerator pulls soil plugs from compacted soil, water will percolate faster into the ground, reducing runoff and erosion. 

Nutrients from fertilizers or compost also reach the root zone, giving your turf the necessary nutrition to prepare for winter. Oxygen also gets down deep, helping roots and soil microbes breathe easier.

Finally, roots also get a direct benefit. When soil is loose, roots spread out more quickly and go deep belowground to find extra moisture and nutrient stores over winter. 

After core aeration, turfgrass becomes more resilient to heat and drought stresses. Aeration transforms thin, weak turf into a healthier green lawn in the long run.

We recommend you make your overseeding appointment right after your aeration service to get those seeds in the deep holes aeration provides.

All About Overseeding: The Perfect Follow-Up to Aeration

We’ll put down grass seed on your lawn at your overseeding appointment. Most turfgrass, after the long, hot summer, can look patchy. We solve this problem by overseeding your property with a turfgrass blend that grows well in Bucks and Montgomery Counties.

One of our lawn care technicians will assess your Chalfont, Warrington, or Warminster lawn to see what areas need grass seed. 

At Jamison Lawn Care, we match our seed blend with your existing turf so your lawn looks uniform. We provide two types of cool season turfgrass blends:

  • Fescue Seed Blend

This turfgrass blend is typically used on newer lawns, and we recommend this blend for all new home lawns. Many new homes already have this blend in their yards, so color and grass type match up nicely.

  • Kentucky Bluegrass Seed Blend

Many established lawns in the area have a Kentucky Bluegrass turfgrass blend. Our seed blend harmoniously fills bare patches and produces an even color with your yard.

How to Maintain Your Lawn Post-Aeration and Overseeding

We coach our clients on caring for their newly seeded lawns. 

It takes about 10-14 days for turfgrass to germinate. You must water your lawn daily and soak it to 1”. Use a ruler or a soil probe to see if you’re adding enough moisture to soak the topsoil.
